Ubuntu :: Loop Through Subfolders And Execute Commands Or Scripts?
Apr 3, 2010
Let's say I have 4 subfolders in the folder test as shown below:
drwxr-xr-x 2 muskedear muskedear 4096 2010-04-03 17:11 sub001_p1
drwxr-xr-x 2 muskedear muskedear 4096 2010-04-03 15:38 sub002_p1
drwxr-xr-x 2 muskedear muskedear 4096 2010-04-03 15:38 sub001_p2
drwxr-xr-x 2 muskedear muskedear 4096 2010-04-03 15:38 sub002_p2
I want to loop through the folders and check if they end with *_p1 or *p2. If a given folder ends with *p1, I want to cd to that folder and manipulate certain files in that folder. If the folder ends with *p2, I want to perform different manipulations on certain files.

I am having trouble getting the while loop to execute in the ssh command:ssh $USERID@serverX "while read line do echo $line done<$list_dir/cost_feed.lst.old"Error:bash: -c: line 1: syntax error: unexpected end of fileI have managed to use simpler commands with ssh like:ssh $USERID@serverX "pwd; cp x y"I expect that I need to add some combination of escape characters or semicolons

One of my servers needs to issue an "apt-get update" command on each of the clients in a lab. However, after the first update, it exits. In trying to replicate the problem with a simpler script, I created the following which fetches the listings of multiple directories from a client:
NUM=0
cat paths | while read DIR; do
ssh server-name ls $DIR > /tmp/$NUM.txt
NUM=`expr $NUM + 1`
done
Again, after the first iteration, the script exists. I tried the following line too, but it made no difference:
bash -c ssh server-name ls $DIR > /tmp/$NUM.txt
The only thing that worked so far is this
xterm -e ssh server-name ls $DIR > /tmp/$NUM.txt

how to execute commands on startup. I've added lines to /etc/rc.d/rc.local, /etc/rc.local, I've put scripts (with extension .sh) into /etc/init.d/ and I've set the executable permission thing on all of them with chmod -x. I *still* can't get anything at all to execute on startup. The truth is, I'm trying to enable multitouch and button tapping automatically when I startup Fedora. I have the commands
[code]...
Which I want to execute whenever I start Fedora (it's a bit tedious to write them every time, or even to have to execute a script myself whenever I start my computer). Furthermore, if I can figure this out, then I can do all sorts of things. Does anyone have a clear, surefire way in which I can do this? I'm not good with using Linux at all

I am trying to determine if I should upgrade PHP's PEAR on my server. I am trying to check the version of PEAR currently installed. I am getting the following error when I use the pear -V command:Warning: realpath(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s)(/usr/share/pear:/usr/share/php) in System.php on line 459I tried adding /tmp to my php.ini file, but then when I use the pear -V command it doesn't do anything. I do not get any errors or anything.I am also trying to install symfony and have the same situation described above when I use the following command: pear cannel-discover pear.symfony-project.comDoes anyone have any thoughts? If not the solution, does anyone have any suggestions on how to begin troubleshooting this?

I can ssh to the remote computer OK, but the commands execute on the local machine, not the remote machine as they should. After much frustration I did the following hoping to clear the problem. I turned off all machines on my LAN, the hub and the router. I then rebooted everything in the reverse sequence - cable modem, router, hub, and then the computers.Then I reinstalled ssh on both machines.
sudo apt-get purge openssh-server openssh-client
sudo apt-get install openssh-server openssh-client
sshd in now running and port 22 shows on both machines. However the problem persists.

I'm looking to, all in the course of one batch file:
ssh into a remote computer execute commands (per the batch file) on the remote host.
What options do I need to add to the ssh invocation so that the batch file executes the lines following the ssh invocation over the connection?
e.g., with sftp it's simply adding a -b /dev/stdin and then << EOF at the end; how do I do this with SSH?

I have debian lenny, when I run an application is slow to load (example: iceweacel open and it takes, I can hold him iceweacel work normally), I tried to change from gnome to another and the same thing, went down some services (samba, squid) and nothing. I open a terminal and it takes, I want to duplicate it and do it fast. From a terminal without X (tty1) with root run mc and moves quickly, also run as root "sudo mc" and takes to boot.Any action done with sudo it takes to run.Can not be what it takes to make starting the applications, not the PC because it is new, and from one moment to another I began to pass this

Customer asked me to create a menu for linux he also asked me to do this: Open like a command like where a user can execute commands...so for this the users have sudo enabled. The code below works OK. But it has an issue when a command is executed but the command does not need sudo
Like for instance
Code:
cd /
sudo: cd: command not found
How can I allow a user to execute all commands when a command does not need sudo
Code:
echo -e "Press Control+C to finish"
#echo -e " "
while true;
do
read whichcmd?"Insert Command: "
sudo $whichcmd
done

I am trying to get F10 installed on L2 so that I can use the system the same way that I have been using L1 with F8. Specifically, I am using unison (with ssh) to crossload files between the desktop and the laptop. Unison works just fine when executed on the desktop crossloading to the F8 Laptop1. But when trying to do the same on L2, it hangs while trying to contact the server.Attempting to diagnose the problem has led me to ssh.I can use ssh to login to any of my systems from the desktop. E.g.,ssh delta
but attempting to execute a command via ssh simply hangs. E.g.,ssh delta "echo $PATH"
Both ssh login and ssh remote execution work fine when done to the F8 laptop 1.
I have installed tcsh on all systems and my login shell is csh (i.e., tcsh) on all machines.I have spent the better part of the last two days trying to find something but have failed. As far as I can tell, both L1 and L2 are configured identically:
firewall disabled
selinux disabled
and while I have not done a character-by-character comparison of the ssh and sshd configuration files, they appear (visually) to be the same, as shipped with the Fedora distribution.
I need some pointers on where to look for problems, etc.

I just finished installing Fedora 11 on a Dell Inspiron 6000. After some tinkering, I was able to get the Broadcom 4318 wireless card to start working. After a restart, I booted into Fedora and attempted to connect to my wireless network.Five seconds later Fedora freezes. I cannot move the mouse, execute any commands (except hold the power button down), or access any log files. The only confirmation I get is that my router does receive a signal from the wireless card, shortly before dying.
